Property, Plant and Equipment [Abstract]

Property and equipment are stated at cost. Equipment held under capital leases is stated at the present value of minimum lease payments at the inception of the related leases. Depreciation for buildings and improvements is recognized under the straight-line method over 20 to 40 years or, for leasehold improvements, over the remaining term of the lease plus renewal options for which failure to renew the lease imposes a penalty on the Company in such an amount that a renewal appears, at the inception of the lease, to be reasonably assured. The primary penalty to which the Company is subject is the economic detriment associated with existing leasehold improvements which might be impaired if a decision is made not to continue the use of the leased property. Depreciation for movable equipment is recognized over useful lives of three to ten years.
